OWASSO, Oklahoma - A firefighter had a closer view than he wanted of a tank explosion in Owasso; and because he had a camera on his helmet, we can see exactly what he saw.

Limestone Fire Captain Don Boyle was as close to the tank that exploded as anyone and recognizes he's fortunate he wasn't hurt.

He was monitoring two firefighters putting water on one tank, and figures he was about 40 yards away when a pressure valve blew, and then the end of the tank blew off.

Boyle said everyone on scene thought the tank was safe, but because of what happened, he's certain the video will be used for training all over the country.

The Occupational Safety and Health Administration said they are investigating the explosion.
